To avoid power disruptions, all generators in a power grid must be synchronized. Here, the authors propose a mathematical approach to calculate all stable states of the lossless real power flow equations, which provide insights into the widely used linear power flow approximation and factors that limit the stability of power grids.

Disrupting the paradigm that metallic materials make poor thermoelectrics, electronic transport modeling suggests that some metals can have ultrahigh thermoelectric power factors. This is enabled by electronic structures which impose carrier filtering via selective scattering by heavy bands.
